LM10UU 10mm Linear Motion Bearing for 3D Printer LM10UU 10mm Linear Motion Bearings are perfect for linear motion on your 3D Printer, CNC, or other applications. It provides a precise, safe, and reliable linear motion system. This is Linear Motion Bearing closed type ball bushing that has a 10mm bore and 19mm outer diameter and is suitable for use in a mounted slide unit to carry components. These Bearings have various standardized parts which are interchangeable, so you need not worry about the replacement of any worn parts. LM 10 UU Linear Motion Bearing is High Precision and Rigidity linear motion bearings are produced from a solid steel outer cylinder. Also, the linear motion bearing incorporates an industrial-strength resin retainer. LM10UU Linear Motion Bearing is Ease of Assembly The standard type of linear motion bearing can be loaded from any direction. This Linear Motion Bearing is a linear motion bearing that consists of an outer cylinder, ball retainer, balls, and two end rings. The ball retainer which holds the balls in the recirculating trucks is stored inside the outer cylinder by end rings. Those parts are assembled to optimize their required functions.
